BACKGROUND Agro‐industrial co‐products rich in lignocellulose, for example cassava petiole (CP) waste, have high potential as sources of porous carbon materials, alongside other impressive advantages, including ease of acquisition, abundance and availability, renewability and low cost. This work shows the successful treatment of mesoporous carbon with rod‐like structure derived from agro‐industrial CP waste carbonized and physically activated by direct one‐stage integrated pyrolysis using a zinc chloride (ZnCl2) activator agent, in the production of a supercapacitor electrode for energy storage. The ZnCl2 was tested at varying concentrations, including 0.5, 0.7 and 0.9 mol L–1. The surface morphology, chemical content, surface area and porous size distribution were evaluated to determine the physical properties of activated carbon, and a cyclic voltammetry method was used to assess the electrochemical characteristics using a two‐electrode system in 1 mol L–1 H2SO4 as an electrolyte. RESULTS The porous carbon obtained displayed a rod‐like morphology structure, featuring numerous hierarchical tuneable and well‐confirmed micropores and mesopores. This monolithic material contained predominantly C (87.85%), demonstrating a maximum surface area of 759.816 m2 g−1 at 0.9 mol L–1 concentration. Furthermore, the highest specific capacitance reached was 193 F g−1 at 0.7 mol L–1, with maximum energy and power densities of 26.90 Wh kg−1 and 96.94 W kg−1, respectively. CONCLUSION The novel rod‐like mesoporous carbon derived from CP waste produced using a facile, cost‐effective and sustainable method, without metal–organic framework or templates, shows great potential as an electrode material for enhanced supercapacitor performance. © 2020 Society of Chemical Industry (SCI)

“…The increase is more pronounced in the case of C–KOH sample, which is related to the exceptionally high surface area. Chemical activation of carbon materials leads to the formation of micropores, and it has been well demonstrated that the ion confinement in the micropores can lead to the higher capacitance [ 50 , 51 , 52 , 53 ]. The increase of the scan rate from 10 mV s −1 to 100 mV s −1 leads to the significant distortion of the CV curve shape and the essential decrease of capacitance values for C-non and C–CO 2 samples.…”

In this work, we present the preparation and characterization of biomass-derived activated carbon (AC) in view of its application as electrode material for electrochemical capacitors. Porous carbons are prepared by pyrolysis of chestnut seeds and subsequent activation of the obtained biochar. We investigate here two activation methods, namely, physical by CO2 and chemical using KOH. Morphology, structure and specific surface area (SSA) of synthesized activated carbons are investigated by Brunauer-Emmett-Teller (BET) technique and scanning electron microscopy (SEM). Electrochemical studies show a clear dependence between the activation method (influencing porosity and SSA of AC) and electric capacitance values as well as rate capability of investigated electrodes. It is shown that well-developed porosity and high surface area, achieved by the chemical activation process, result in outstanding electrochemical performance of the chestnut-derived porous carbons.

“…Furthermore, AC based pitaya peel had a high specific surface area up to 1872 m 2 /g obtained from chemical activation procedure also using KOH solution. 60 The AC displayed a capacitance of 255 F/g, alongside outstanding cycle life stability with 96.4% capacitance retention after 5000 cycles. The results indicated that the bio-waste like pitaya peel could be utilized for a cheaper alternative for supercapacitor electrode materials.…”

A suitable electrode or active material is one of the promising ways to boost supercapacitors' efficiency. The right properties of the electrode materials will enhance the performance of the supercapacitors. New electrode materials such as biomass-derived carbon, mesoporous materials, and transition metal nitrides have been studied as potential substitutes for the most common electrode material, activated carbon. This review discusses the recent (5 years) progress of the electrode materials in supercapacitors compiling the literature from 2016 to 2020. The overview of design (structures), recent developments, and challenges of the new electrode materials are presented in this review with considerations on their electrochemical performance in supercapacitors.
